Prior to 3.7.14 and 4.1.10, a vulnerability was identified in the Twig sandbox security policy that allowed database write operations when cms.safe_mode is enabled. Backend users with Developer permissions could use Twig template markup to execute insert, update, and delete operations on any database table through the query builder, which is included in the sandbox allow-list. This vulnerability is fixed in 3.7.14 and 4.1.10."

Antes de 3.7.14 y 4.1.10, se identificó una vulnerabilidad en la política de seguridad del sandbox de Twig que permitía operaciones de escritura en la base de datos cuando cms.safe_mode está habilitado. Usuarios de backend con permisos de Desarrollador podían usar el marcado de plantillas de Twig para ejecutar operaciones de inserción, actualización y eliminación en cualquier tabla de la base de datos a través del constructor de consultas, que está incluido en la lista de permitidos del sandbox. Esta vulnerabilidad está corregida en 3.7.14 y 4.1.10."
